Does the job
Worked fine for me, as the hole to be enlarged was in fiberglass, therefore relatively soft. Not sure it would work as well with hard metal. The Automatic Spring Loaded Center punch is a convenient little tool to have

Good quality.

Low price - low quality
The quality is very low. Only suitable for plastic or very thin metal. But for such a low price, it's not bad.

Wrong size in the kit.
I received two types of 4-12 and a 4-20 but no 4-32…
